Hydridotris(pyrazolyl)borate Ruthenium(II) Complexes Containing Phosphine or Phosphite Ligands
Jocelyn Lanorio, Illinois College
This course-based research will introduce students in an advanced inorganic chemistry course to air-sensitive and catalysis. Students will examine a series of ruthenium(II) hydridotris(pyrazolyl)borato complexes with phosphine or phosphite ligands using modern instrumentation and specialized equipment such as Schlenk line and drybox. The first two meetings should be devoted for literature search, familiarization of instrument operation, and selection of phosphine or phosphite ligand along with student submitting proposal that contains the safety protocols and handling of the chemicals involved in their selected system. Four meetings will then be designated for the synthesis and characterization of the complex. The students run catalytic and control reactions and determine the percent yield of the product using 1H NMR. The synthesis and catalytic conditions are modified from previously published research articles. This experiment combines complex synthesis, characterization, data analysis and data sharing.
